Specification of Letters Patent.

Patented Nov. 5, 1918.

Application filed December 17, 1917. Serial No. 207,473.

To all whom it may concern:

Be it known that we, Howann H. Gnoss, Jr., a citizen of the United States, and HAROLD L. BATTING, a subject of the King of Great Britain, respectively, residing at Chicago, in the county of Cook and State of Illinois, and at Memphis in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Lamps, of which the following is a specification.

Our invention relates to improvements in lamps or light projectors.

One of the objects of our invention is to improve devices of that character, having especial reference to improvements in the structure such as disclosed in our Patent No. 1,211,047 granted January 2nd, 1917, for light projectors.

Another, and more specific object of our invention is to make the projector, reflector and closure rim of the casing in one piece and so arrange the structure that the inclination'of the reflector may be varied or adjusted without moving the casing.

Other and further objects of our invention will become readily apparent to persons skilled in the art from a consideration of the following description when taken in" conjunction with the drawings, wherein Figure 1 is a central vertical section of the device in its simplest form.

Fig. 2 is a plan view of a fragment showing the manner of connecting the rim of the casing to the casing proper.

Fig. 3 1s a section taken on line 3-3 of Fig. 1. I

In all the views the same reference characters are employed to indicate similar parts.

In our present invention we have materially reduced the number of parts requisite ,for the projector structure, cheapening the cost of construction and arranging the cooperative members in such manner as to be readily'and quickly assembled and ad justed whereby to change the inclination of" the rays of light, with reference to the roadway, projected from the lamp.

In the present exemplification of a preferred embodiment we make the parabola or projector,the reflector and a glass-holding rim for the closure, all in one integral piece,

' preferably of sheet metal, and arrange a very simple means for changing the inclispans the slot 16 in the casing 5.

suitable projections whereby it may be supported; which projections are not shown for the reason that they do not constitute apart of our invention.

The casing is round and terminates at its open end, preferably, as at a raw edge 6, which is to be covered by a rim 7, that is adapted to hold the glass 8 of the closure. The projector 9, and the reflector 10, are integral parts of the rim 7. The inner annular shoulder 10 of the rim 7 is provided to receive an annular packing ring or cushion 11, which may be of rubber, cord or the like, to protect the closure glass 12. Another shoulder 13 is provided to receive an annular spring wire 1 1 that is tobe sprung into the opening 15, in front of the glass, to hold the latter in place. The lower part of the shell 5 is provided with an elongated slot 16 to receive a lamp socket 17, carried by the parabola, for the lamp 18. A screw 20 passes through the lower portion of the rim 7 and carries a cross bar 21 which The lower threaded end of the screw 20 carries a thumb nut 24 whereby to tighten and hold the rim,

and the reflector 10 in adjusted positions with reference to the casing 5. The pro-- jector 9 is provided with a down-turned flange 25 to receive and hold a socket 17, and through which the lamp 18 is passed to enter the socket.

lVhen the reflector 10 is to be inclined to a greater or less extent from the perpendicular, in order to vary the inclination of the light rays projected from the device, the rim 7 is pushed toward the casing 5 or pulled away from it so as to change the position of the reflector 10 and is secured in the changed position by the thumb nut 24. The rim 7 is hinged to the casing 5 by a hinge 27.

When the thumb nut 24 is loosened, so that the rim 7 may be moved away from the casing 5 on the hinge 27, the lamp, including the projector 9 and reflector 10, may be raised vertically upon its supporting hinge 27 so that the lamp will throw its light back into the automobile, when it is desired to project the light in that direction. when the light projectors are used on automobiles. This is frequently convenient when a light is required to facilitate repairs, or to read, or to perform any other service requiring a good light behind the lamp.

By means of this construction, the light emanating from the projector may be thrown into various fields, in front or behind the source of light, or into the air, as a signal, without the necessity of moving the shell, or casing 5, on its support. \Vhen the parts are in the position shown in Fig. 1, the device will project its light in planes below the horizontal plane taken through the top of the reflector 10. This is satisfactory and all that could be desired, when the automobile is operatlng u )on practically smooth even roadways but w en going up or down a hill, it is convenient to have the inclination of the light rays vary. \Vhen going up the hill the light should be thrown into planes at an upwardly inclined angle and when going down hills, it should be thrown at an angle downwardly inclined. Of course, this could be done by mechanism connected to the pivotally movable source of light consisting of the projector, reflector and rim, carrying the lamp.

lVhile we have herein shown a single embodiment of our invention for the purpose of clear disclosure, it is manifest to persons skilled in the art, that changes may be made in the general form, configuration and dis position of the parts, within the scope of the appended claims.

Having described our invention, what we claim is 1. A lamp comprising a casing; a light projector; a source of light located at substantially the focal point of said projector; a substantially flat reflector inclined to the axis of said projector and positioned to intersect and reflect the rays of light from the light projector and means to adjust the inclination of said reflector in said casing without changing the relative positions of the projector and reflector and without moving the casing.

2. A lamp comprising a casing, a closure for said casing comprising a rim and a glass plate carried thereby, a light projector with its axis in a vertical plane, a reflector in clined to the axis of said projector for intercepting and reflecting the rays of light therefrom, said projector and reflector being integral parts of the rim and means to adjustably secure the composite structure to the casing whereby to adjust the inclination of the reflector.

3. A lamp comprising a casing, a closure for said casing comprising a rim and a glass plate carried thereby, hinged to the upper part of the casing; a light projector with its axis in a vertical plane; areflector-inclined to the axis of said projector for intercepting and reflecting the rays of light therefrom, said projector being integral parts of the rim and means for adjusting the composite structure to change the inclination of the reflector.

4. A lamp comprising a casing, a rim for a closure hinged to the top of the casing, a projector near the bottom of the rim, an overlying inclined reflector near the top of the rim, said rim, projector and reflector, formed of a single piece of sheet metal, and a lamp holding means at or near the focal point of said projector.

5. A lamp comprising a casing having a slot near its bottom edge to admit a lamp socket, a rim overlying the open end of the casing and hinged thereto, a projector near the bottom of the rim with its axis in a vertical plane, a reflector overlying said projector, inclined, at an angle to said axis, said projector and reflector carried by said rim and removable from said casing when said rim is moved on its hinge and a lamp socket carried by said projector and located near the focal point thereof, adapted to enter the slot in the casing when the casing is closed and means to adjustably hold the rim inpositionwith relation to the casing to adjust the inclination of the reflector.

In testimony whereof we hereunto set our hands.
